Why this recipe works
- Peanut butter base- These bars have a thick and chewy peanut butter cookie base made with real creamy smooth peanut butter.
- East to make- This recipe requires only basic baking skills! All you do is mix the ingredients and pour them in a pan! It’s as easy as that!
- Jam filling- I use a store bought filling for this recipe. I like strawberry, but you can use whatever flavor you want!
- Shortbread crumb topping- The shortbread crumb topping is my favorite part of this dessert. It adds a crunchy texture and just brings the whole thing together.

Grocery list
Here are some pantry items that you may not have on hand. For a full list of ingredients, check out the recipe card below.
- Large eggs- You should pull these out 2-4 hours before you start baking to bring them to room temperature. You will use a whole egg and an egg yolk.
- Unsalted butter- As always, I use unsalted butter to help control the amount of salt in my recipes.
- Smooth peanut butter- I always use Jif. It’s my favorite.
- Light brown sugar- I always use light because it helps give the cookie a light flavor.
- Strawberry jam- Use whatever kind/flavor of jam that you prefer!

Step By Step Instructions
Here is how to make and bake these dessert bars. I use a small food processor, but If you don’t have one, you can totally use a pastry cutter.
Step 1: Whisk the butter and sugars. In a large bowl, whisk the melted butter, granulated sugar, and brown sugar until well combined. Whisk in the peanut butter. Whisk vigorously for about 30-45 seconds.
Step 2: Add the egg, egg yolk, and vanilla. Add the egg, egg yolk, and vanilla and whisk them together.
Step 3: Fold in the dry ingredients. Switch to a rubber spatula and fold in the flour, salt, and baking powder.
Step 4: Press dough into pan. Press the dough into an even layer in the prepared pan. Spread the jam with the back of a spoon to evenly cover the top of the peanut butter bars. Set aside while you make the shortbread crumb topping.
Step 5: Make the shortbread crumbs. In a large bowl, stir together the flour, sugar, and baking powder. Set aside.
Step 6: Combined the butter and the flour mixtures. If you have a food processor, add the flour mixture and the cold butter and mix it until it turns into coarse crumbs.
Step 7: Add the egg. Add the egg and blend until it fully comes together. If you need to break up bigger pieces, use your fingers to break them up.
Step 8: Add the crumb topping and bake. Add the crumbs to the top of the jam/peanut butter bars and bake for 40-50 minutes. The top should start turning light brown. When you insert a toothpick, it should come out with little, to no, crumbs.

Assembling the bars
-First prep your pan by using binder clips and parchment paper. Clip the parchment paper to the edges of the pan. Spray the parchment paper with cooking spray.
-Evenly press the peanut butter dough into the prepped pan.
-Top with the jam. With the back of a spoon, evenly spread it across the top of the peanut butter dough.
-Top with the crumb topping and bake for 40-50 minutes.
Expert baking tips
Flour- Make sure the flour is spooned and leveled. This is a more accurate way of scaling the flour.
Use a good pan- Use a high quality pan. I got mine here: I suggest not using a glass pan because a glass pan crisps up the edges more.
How to cut- Use a clean knife and clean the knife with a paper towel after each cut.
Bake low and slow- I turned my oven down to 325 for these bars because I wanted them be perfectly baked.
Storing and freezing
These Peanut Butter and Jelly Bars can be stored in an airtight container or ziplock bag for up to 5 days at room temperature. You can also place them in an airtight container in the fridge for up to one week.

Freezing
They can be frozen in an airtight container for up to 2 months.
If you do choose to freeze them, I suggest pulling them out two hours before you want to eat them and letting them come to room temperature.
